BOOK-EDGE-GILDING PRESS.

SIECIIFICATION forming part of Letters Patent No. 711 ,490, datedOctober 21, 1902.

' Application filed July 28,1902. Serial No. 116,638. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, WILLIAM GIENow, a citizen of the United States, anda resident of New York city, (Bronx,) county and State of New York, haveinvented certain new and useful Improvements in Book-Edge-GildingPresses, of which the following is a specification.

This invention relates to a book-edge-gilding press which is providedwith a swinging book-holding frame that permits both edges of the bookto be successively exposed and gilded without opening the press. In thisway time and labor is saved and the manipulation of the work is greatlysimplified.

The invention consists in the various features of construction pointedout in the claims.

In the accompanying drawings, Figure 1 is a front elevation-of myimproved press; Fig. 2, a side elevation thereof; Fig. 3, a plan; Fig.4, a cross-section of the clamping-frame on line 4 4, Fig. 3; Fig. 5, asimilar section with the books in position; Fig. 6, a detail of one ofthe double concave blocks; Fig. 7, a

section on line 7 '7, Fig. 3; Fig. 8, a section of the frame andplatform on line 8 8, Fig. 3; and Fig. 9, a horizontal section on line 99, Fig. 8, with the boards removed.

The frame of the press consists, essentially, of two parallel beamsorsupports at, having legs a, which are mounted upon the baseplates oThe beams CL constitute at their center the bearings a for the trunnionsb of a bottomless swinging frame B, which constitutes the clamp of thepress and may be locked in its horizontal or slightly-inclined positionby a catch B. This frame is composed of a fixed jaw 19, an opposingmovable jaw 5 a pair of guide-rails b and a connecting-piece 17 Thefixed jaw b and the connecting-piece b are firmly attached tooppositeends of the guide-rails while the movable jaw 11 is guided alongsaid rails. In order to draw themovable jaw toward the fixed jaw, andthus clamp the work to the press, I employ a shaft a, hung in bearings cof frame B. This shaft may be rotated in suitable manner-such, forinstance, as by a handle 0 having a pawl 0 that engages ratchetwheel 0fast on shaft 0, said ratchet-wheel being likewise engaged by a detent cpivoted to frame B. To the shaft 0 are secured the ends of a suitablenumber of chains d, that pass around pulleys e and are then connected tothe fixed jaw 19, Fig. 4. -The pulleys e are hung in the forked ends eof screw- I prefer to arrangethe books D within the I clamp B in sets,Fig. 5, and interpose between each set a double-concave block f, bymeans of which the pressure of the clamp is transmitted to the edges ofthe books only, while the centers of the books remain free. way I obtainan increased compression at the edges by a reduced amount of power.

In order to support the books while they are being secured to andremoved from frame B, I employ a platform g, which is'vertically movablebeneath said frame. Figs. 8 and 9, is preferably. open and covered byloose boards g, which may be tilted to remove accumulated sediments. Theframe 9 is guided along the uprights a by grooves g and flanges 0%, soas to obtain proper rectilinear movement. It may be raised and loweredin suitable manner-such, for instance, as by a shaft 77., rotatable byhand-wheel h and hung in bearings a of the pressframe. To the shaft hare connected one ofthe ends of four chains 1' ij theother ends of whichare connectedv to the platform g. The chains 2' i extend directly fromeyes g at one end of the platform to the shafth, while the chains j jext'eii'd tos'aid shaft-from eyes g at the op posite end of theplatform. The chains pass over idlers j j j pivoted to the-uprights a.

In order to lock the platform 9 in its elevated position, the shaft hisaxially movable in its bearings 00' and provided with an angularprojection k adapted. to be received by a cor responding angular socketof a lug af. When the chains are wound up and the'platform is raised,the shaft is pushed backward and into engagement with said socket tolock the parts in position. To lower the platform, the shaft h is drawnforward, so that it becomes This platform,-

In this IOO unlocked and the platform may descend by gravity.

From the rails 19 may be suspended the detachable supports 7c, thatcarry the goldcushion.

The operation is as follows: The frame B being in a horizontal orslightly-inclined position, the platform g is raised until the distancebetween the top of the boards g and the center of the frame is equal toone-half the height of the books. The books are now arranged upon theplatform between the opened jaws of the frame B, with the doubleconcaveblocks f interposed, and then the shaft 0 is rotated to close the clamp,Fig. 5. The upper edges of the books are now gilded, and then theplatform g is lowered, so as to permit the frame 13 to be turned aroundin its bearings 61?, and thus expose the lower edges of the books. Afterthese lower edges have also been gilded the platform is again raised andthe clamp opened, so that the released books will be supported upon theplatform and may be removed from the press.

It will be seen that my press is reversible and permits both edges ofthe books to be successively exposed and gilded without being unclamped.In this Way the operation is greatly simplified, while time and laborare saved.

What I claim isp 1. A book-edge-gilding press composed of a support, abottomless c1amping-frame pivoted thereto, and a platform below theframe, substantially as specified.

2. A book-edge-gilding press composed of a support, a bottomlessclamping-frame piv oted thereto, a movable platform beneath the frame,and means for raising and lowering said platform, substantially asspecified.

3. A book-edge-gilding press composed of a support, a bottomlessclamping-frame pivoted thereto, means for operating said frame, meansfor locking the frame, a platform beneath the frame, means for raisingand lowering said platform, and means for locking the platform,substantially as specified.
